Wireless Short Haul Network Master Component Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless short-distance network systems for battlefield simulations face energy inefficiencies due to high energy requirements, leading to limited service life or the need for large, unwieldy batteries, especially when using radio connections like Bluetooth.
Innovation Solution
A communication method where one component acts as a master and others as slaves, with synchronous and asynchronous data transmission in dedicated time slots and channels, allowing the master to reduce energy usage by only actively listening and transmitting when necessary, and incorporating a sleep mode for components to conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radio connection like Bluetooth is used to connect detectors to the subscriber unit, then cable connection damage is avoided, but energy consumption increases significantly
Solution Approach 1:
The master component periodically listens to the operating channel for a specified period of time rather than continuously monitoring, and slaves transmit data in synchronized time slots. This periodic communication pattern significantly reduces energy consumption while maintaining reliable data transmission between detectors and the subscriber unit.
Solution Approach 2:
The system dynamically switches between active transmission/reception states and sleep modes. The master listens only during designated periods and switches off otherwise, while slaves transmit only when data needs to be reported. This dynamic state management reduces energy consumption while maintaining connection reliability.
2Reliability
If continuous listening mode is used by the master component, then data reception reliability is improved, but energy consumption increases
Solution Approach 1:
The master component listens to the operating channel periodically for specified periods rather than continuously. Slaves transmit data in synchronized time slots, ensuring the master receives data reliably during its active listening periods while consuming minimal energy during idle periods.
Solution Approach 2:
The system uses self-organizing synchronized time slots where slaves automatically know when to transmit based on pre-established timing protocols. This eliminates the need for continuous master monitoring while ensuring reliable data reception during active periods.
3Reliability
If synchronous communication is implemented with dedicated time slots, then data transmission reliability is improved, but system complexity increases
Solution Approach 1:
The system implements synchronous communication where slaves transmit data in dedicated periodic time slots assigned to each slave. This structured periodic transmission ensures reliable data reception at the master while using simple timing-based protocols rather than complex arbitration mechanisms.

AI summary
Communication method between components in a wireless short haul network as part of a battlefield simulation, where one component is in the form of a master and the other components (AC1 - AC10, SC1, SC2) are in the form of slaves, and - the slaves (AC1 - AC10, SC1, SC2) transmit data synchronously or asynchronously to the master in an operating channel - synchronous slaves (SC1, SC2) send data in time windows (T1 - T10) firmly associated with them and - asynchronous slaves (AC1 - AC10) send data in event-based fashion.
